Abstract: Fluid transfer systems and processes for using same. In some embodiments, the system can include a mooring structure, a fluid swivel disposed on the mooring structure, and first and second subsea conduits configured to provide fluid communication between first and second pipelines and first and second flow paths defined by the swivel, respectively. The system can also include first and second surface conduits that can provide fluid communication between a vessel storage tank and the first and second flow paths defined by the swivel, respectively. The system can also include a crossover conduit configured to provide fluid communication between (i) the first and second surface conduits, (ii) the first and second subsea conduits, or (iii) the first subsea conduit and an optional third pipeline. The system can transfer a fluid having a boiling point that is less than an ambient temperature at atmospheric pressure to or from the storage tank.

Abstract: Yoke mooring systems and processes for using same. The system can include a turntable connected to and rotatable with respect to a base. A yoke can be connected to the turntable such that the yoke can at least partially rotate about a longitudinal axis of the yoke and at least partially rotate about a second axis that can be orthogonal to the longitudinal axis. A first and second link arm can be connected to the yoke and to a first component of a first and a second releasable connector, respectively. A first and second lifting line can be connected to the second end of the first and second link arms, respectively. A first and second lifting device can be disposed on a vessel and configured to be connected to a second end of the first and second lifting lines, respectively, to lift and lower the link arms and the yoke.

Abstract: A mooring system for mooring a vessel floating on a surface of a body of water. In some embodiments, the system can include a base structure configured to be secured to a seabed, a yoke configured to be pivotably connected at a first end to the base structure about an axis of the base structure, a weight connected to the yoke, a turntable that can include a rotating part configured to be disposed on the vessel and a fixed part, a link arm that can include a first end configured to be connected to a second end of the yoke and/or the weight and a second end configured to be connected to the fixed part of the turntable such that the vessel is rotatable with respect to the link arm about a central axis of the turntable.

Abstract: Mooring systems and processes for using same. In some embodiments, the system can include a first vessel support structure and a second vessel support structure, each disposed on a vessel. Each vessel support structure can include at least one extension arm can be suspended from each vessel support structure. A ballast tank can be connected to each of the at least one extension arms. A first end of a yoke can be connected to the ballast tank and a second end of the yoke can include a yoke head disposed thereon. The system can also include a first mooring support structure and a second mooring support structure, each fixed in place. Each mooring support structure can include a pitch bearing. The yoke heads of the first and second vessel support structures can be connected to the pitch bearings of the first and second mooring support structures, respectively.

Abstract: Systems and processes for recovering a gas from a vessel. The system can include a buoy that can include a fluid swivel assembly. The fluid swivel assembly can have a first swivel section rotatably coupled to a second swivel section. The system can also include a first liquid transfer conduit, a first gas transfer conduit, a second liquid transfer conduit, and a second gas transfer conduit. The first swivel section and the second swivel section can be configured to maintain fluid communication between the first liquid transfer conduit and the second liquid transfer conduit. The first swivel section and the second swivel section can be configured to maintain fluid communication between the first gas transfer conduit and the second gas transfer conduit. The first gas transfer conduit and the second gas transfer conduit can be configured to convey a gas from a vessel to a subsea location.
